FASTENING SUPPLYING MECHANI SM Original Fild Oct. 25, 1924 MENTOR Wfl1Patented Mar. 25, 1930 UNITED STATES ipmem GFFHCE ELMER R. POPE, OFSOUTH HAMILTON, MASSACHUSETTS, ASSIGNOR TOJ 'UNITED SHOE MACHINERYCORPORATION, JERSEY Original application ma October 25, 1924, Serial No.

1928. Serial This invention relates to fastening supplying mechanismsand is illustrated herein as embodied in means for supplying nalls' to ahand-operated nail inserting device.

" herein as supplyingnails to a nail inserting implement of thecharacter disclosed and claimed in Letters Patent of the United States,No. 1,717,402, granted June 18,1929, on my co-pending application Serial-No.' 745,893, filed October 25, 1924, of which this is a'division,although the invention 'is not limited to use in such an implement.

' Featuresof the invention comprise'a novel arrangement by which thepresence of afastening inserting device in operative relation to theoutlet of a source of fastening supply is operative to release a numberof fastenings which then pass from the source of supply to one or moreguldeways carried by the insertlng device, and a novel supporting andpositioning means for a fastening lnserting device, illustrated as aspring clip together with a plurality of gage members arranged tocontact with the surface of'the fastening insert-ing device, each over asmall area, to support and position the fastening inserting device forthe reception of fastenings from the source of supply. I

With the above and other features and ob jects in view, the inventionwill now be described in connection with the accompanying drawings andpointed out in the claims.

In the drawings,

Figs. 1 and 2 are a side elevation and a front elevation, respectively,each with certain parts in section, illustratingfastening supplyingmeans embodying my invention as delivering fastenings to a fasteninginserting implement of the kind disclosed and claimed in said LettersPatent No. 1,717,402. V

The illustrated mechanism for supplying fastenings to a fasteninginserting device is arranged to handle nails which it receives OFEATER-SON, JERSEY, A CORPORATION OF NEW FAsTENINe-snrrLYme MECHANISM 7745,893. 'Divided and. this application filed. May 31, No.'282,033.

from a hopper provided with suitable' mechanism, which maybe of anyusual type, to feed nails to a raceway or raceways 62. As illustrated,there is a pair of these races ways, the lower end of each beingarranged in alinement with a guidewayconsisting of a tube 64. Each tube64 is long enough to contain sufficient nails to charge one ofthe nailreceiving tubes of an inserting device, indicated in broken lines, whichmay be vof the kind illustrated in said Letters Patent No. 1,717,402.The passage of nails from the raceways62 to the tubes 64 of the supplydevice andfrom the tubes 64 to the nail receiving tubes of the nailinserting device is controlled by .the' presence of the nail insertingdevice-with its nail receiving tubes in alinement with the tubes 64 0fthe supply device.

' In order that the nail inserting device may be properly held inposition, a spring clip 66, with its front'open, is arranged" readily toreceive andto permit the removal of the nail inserting device. Threegage members 68are provided With their surfaces so located that when thenail inserting device is inserted in the clip 66 and is pushedrearwardly against these gage surfaces, it will be properly positionedrelatively to the nailsupply means. For this purpose it is onlynecessary that each of the gage members engage the nail inserting deviceover a small area.

When the nail inserting device is inserted in the clip 66 for thereceptionof fastenings, its upper end engages a pair of lugs 70 carriedby a slide 72 mounted in a bracket'74 of the supply device. A spring 7 6housed in the bracket 7 4 tends normally to push the slide 72 outwardlyso that portions ofthe slide are positioned beneath the outlet of thetubes 64 and prevent the passage of nails from these tubes. On the otherhand, when the slide 7 2 is pressed inwardlyagainst the spring 76 by theinsertion of the nail inserting device, the

slide 72 passes out from under the outlets of the tubes 64 and the nailsin those tubes are free to drop device.

A pair of pivotally mounted stops 80 (the upper endof the left-handoneof which is broken away in Fig. 2) are arranged for into the tubes ofthe inserting movement into the path of feed of the endmost nail in eachraceway 62. The stops 80 are fast upon a rock shaft 82 normally held bya spring 84: in the position shown in Fig. l, in which the stops arejust out of engagement with the fastenings in the raceways 62. An arm86, also rigid with the rock shaft 82, engages the upper end of a rod 88mounted for sliding movement with its lower end resting upon a camsurface 90 carried by the slide 72. Thus when the slide 72 is movedrearwardly, the rod 88 moves downwardly, the stops 80 rocking under theinfluence of the spring 8& into position to prevent the passage P ofnails from the raceways 62 into the tubes 64. At the same time, thenails in the tubes 64'drop' into the tubes of the nail inserting device.WVhen the nail inserting device is removed, the slide 72 is moved out bythe spring 76 into position to prevent the passage of nails from thetubes 6a, at the same time moving the rod 88 upwardly and rocking thestops 80 out of engagement with the nails in the raceways 62 so that thenails in the raceways may move downwardly filling the tubes 64.

While the invention is illustrated herein as embodied in a deviceadapted to handle nails of considerable size, for example nails such asare used for attaching rubber heels to shoes, it should be understoodthat its utility is not limited to the handling of fastenings of thischaracter.

Having described my invention, what I claim as new and desire to secureby Letters tenings from the raceway to the guideway,
